R2006b
21-18
• There are new syntaxes for importing from and exporting to the library's internal
single- and double-precision wisdom databases. These are as follows and are
documented in the reference page for the MATLAB fftw function:
• str = fftw('dwisdom')
• str = fftw('swisdom')
• fftw('dwisdom', str)
• fftw('swisdom', str)
Compatibility Considerations
FFTW version 3.1.1 does not support wisdom produced by previous versions of the FFTW
library. For this reason, FFTW wisdom that has been exported from a previous version
of MATLAB cannot be imported successfully in MATLAB R2006b. Trying to import “old”
wisdom results in a warning.
Future Obsolete Functions
The betacore function generates a warning message in R2006b but completes
successfully. This function will be made obsolete in a future release.
Compatibility Considerations
You should remove all instances of the betacore function from your M-file program
code. This function will not be supported in a future release of MATLAB.
Obsolete Functions
The following uses of MATLAB functions are obsolete as of this release. Attempts to
use this functionality in the R2006a release generate a warning message but complete
successfully. In R2006b, these operations fail and generate an error message.
• The following functions in their entirety: bvpval, quad8, table1, table8, bessela
• The sort function, when used with complex integer inputs
• The gt, ge, lt, and le functions, when used with complex integer inputs
• The beta function, when used with 3 inputs
• The gamma function, when used with 2 inputs
